Tottenham fear key defender Jan Vertonghen will miss a significant chunk of the title run-in after sustaining a nasty looking ankle injury.
The Belgium international looked crestfallen as he was helped off the pitch after rolling over his left ankle in trying to stretch for the ball in the 4-0 win over West Bromwich Albion.
Manager Mauricio Pochettino confirmed the central defender had damaged ankle ligaments.
Vertonghen has a history of ankle problems, missing Euro 2016 with a similar injury.
